Example Embodiment

[0011] exist figure 1 In the figure, the left side of the vertical dotted line is the circuit diagram related to the control inside the switch room, and the right side of the vertical dotted line is the circuit diagram related to the control outside the switch room. The indoor related control means that the original 1K, 20W current limiting resistor is cancelled in the circuit. The current limiting resistor in the original circuit was moved outdoors and replaced by an electric locking electromagnet. The locking force of the DDS electric locking stopper is set to 30KN. The DDS electric locking stopper can not only limit the current, but also reliably lock the switch while checking the indication. The indoor related control indicates that the original second group of contacts of the 1st start relay in the circuit is redundant. When the 1st start relay is picked up, the power carrier data transmission switch module obtains the information that the train controller intends to ac...

Abstract

The invention relates to a maloperation-proof cipher adhesive detector. For overcoming the possibility of midway transformation for turnout junction in the prior art, the cipher adhesive detector provided by the invention can detect a turnout junction cipher, two electronic control stoppers are additionally arranged on switch equipment under the condition of corresponding with the failure safety principle, wherein one electronic control device is an electricity-obtaining locking stopper, and the other electronic control device is an electricity-loss locking stopper. The reliable locking of the turnout junction is performed by the electricity-obtaining locking stopper, the electricity-loss locking stopper and a power carrier wave digital switch module, the possibility of midway transformation for the turnout junction is eradicated; and the power carrier wave digital switch module transmits back the position information of the switch device, thus the driving safety is ensured further.

Description

Technical field [0001] The invention relates to an on-site operating mechanism of a turnout, in particular to a closeness checker which can not only check the tightness of the turnout, but also prevent the misoperation of the turnout. Background technique [0002] In the prior art, 200910151208.2 provides a close-fit checker, in which a close-fit check contact is provided on the indicating rod of the switch device or the subsidiary mechanism of the indicating rod. Like all the close-fitting checkers in the prior art, the close-fitting checker only checks the tightness of the switch, but cannot reliably lock the switch outdoors. When the signal cable is in series, the pin is squeezed or the hook locker is broken, or the connection point is artificially sealed, there is a possibility that the switch may be switched midway. In fact, several train overturning accidents have occurred, which seriously affect the driving safety. Contents of the invention [0003] In order to ove...
